The 22-year-old star has broken up with her 18-year-old boyfriend, the son of Robert F. Kennedy Jr. and the late Mary Kennedy, Us Weekly and other outlets have reported.

A representative for Swift did not respond to ABCNews.com's request for comment.

The pair began dating this summer, and their relationship quickly progressed. They were spotted around the Kennedy family home in Hyannis Port, Mass., throughout the summer kissing and spending time with his family.

Things were going so well that Swift reportedly bought a home next to the Kennedy compound in Hyannis Port.
